Chemical structures known as sandwich complexes generally consist of two planar molecular rings (aromatic ligands) on either side of a central metal ion. This situation is reminiscent of a sandwich, ...

Chemists have presented a new approach in which a single carbon atom is inserted into the carbon skeleton of cyclic compounds in order to adjust the ring size. The method could be relevant, for ...

Cycloaddition reactions are an efficient strategy for constructing cyclic compounds that are important building blocks for other chemicals. In these processes, π-electrons from different unsaturated ...

A high-yield, one-pot, scalable reaction facilitates the production of biologically relevant amide compounds using less reactive nitrogen-containing heterocyclic compounds and carboxylic acid without ...
